基于多体系统动力学的实时仿真模型可以高精度地再现现实。由于实时模型通常描述与复杂环境交互的机器，因此具有仿真模型在其中操作的准确环境模型是重要的。摄影测量提供了一组工具，可用于从平面图像创建三维环境。创建的环境和基于多体的仿真模型可以在Unity环境中组合。介绍了一种基于现有真实的环境生成精确空间工作环境的方法。作为一个数值例子，详细的环境模型是从一个大学校园区创建的。
Real-time simulation models based on multibody system dynamics can replicate reality with high accuracy. As real-time models typically describe machines that interact with a complicated environment, it is important to have an accurate environment model in which the simulation model operates. Photogrammetry provides a set of tools that can be used to create a three-dimensional environment from planar images. A created environment and a multibody-based simulation model can be combined in a Unity environment. This paper introduces a procedure to generate an accurate spatial working environment based on an existing real environment. As a numerical example, a detailed environment model is created from a University campus area.
